Specification of Letters Patent.

Patented Aug'. 18, 1914.

Application filed January 28, 1914. Serial No. 815,016.

T0 all whom t may concern Be it known that I, WILLIAM F. GIBBARD, a citizen of the United States, residing at Fruitvale, in the county of Alameda and State of California, have invented a new and useful Sash-Lock, of which the following is a specification.

The present invention `appertains to sash locks or fasteners, and aims to provide a novel and improved contrivance of that character.

It is the ob] ect of the `present invention to provide a unique sash fastener so constructed and operable, that the lower sash of a window may be locked at various positions, and whereby the upper sash may be locked to the lower sash at' vari-ous positions, the two sashes being capable of being locked independent of each other.

A further object of the present invention is to provide a unique locking device adapted to be carried by the meeting rail of the lower sash, and embodying a pair of independent manuallyv operable latches or catches, which are arranged to engage racks carried by the parting strip and stile of the upper sash, respectively, to the ends above noted.

It is also the object of the present inventionv to provide a sash lock of comparatively simple, compact and inexpensive construction, which shall be simple, convenient, practical and eflicient in its use.

With the foregoing and other objects in view, which will be apparent as the nature of the invention is better understood, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. i

The invention has been illustrated in its preferred embodiment in the accompanying drawings, wherein- Figure 1 is a horizontal section of a fragmental portion of a window structure, illustrating the present invention applied, portions being broken away. Fig. 2 is a fragmental elevation of the parts depicted in Fig. 1. Fig. 3 is a longitudinal section of the lock. t

In the drawings, the numeral 1 designates the j amb of a window structure, and the numerals 2 and 3 designate the lower and upper sashes respectively.

In carrying out the present invention, the parting strip or bead 4 is in the form vof a channel, pressed from sheet metal, and having its flanges engaging the groove or slot in the jamb 1, the bend of the channel being exposed to properly guide the sashes, and being provided with a series of transverse slots or openings 5 forming a rack.

An upright sheet metal channel member 6 is disposed against the inner face of the stile of the upper sash, the channel 6 having its flanges or edge portions engaging the stile, and the said channel being spaced from or parallel with lthe parting strip 4. That flange of the channel 6 nearest the parting strip, is provided` with a longitudinal series of transverse slots or openings 7, and screws or other securing members 8 are passed through the bend of the channel 6 to take into the stile of the upper sash for retaining vthe channel or rack 5 in position. The meeting rail of the lower sash is provided with a notch or slot 9 through which the rack 6 is adapted to slide, when the lower sash is raised, or when the upper sash is lowered.

The lock forming the gist of the present invention, embodies a case of parallelogram contour. The case includes the base or bottom 11 having the upstanding sides or angeslQ at its edges, and a top or cap plate 13 resting upon the sides or flanges 12. The sides 12 terminate short of one end of the case, to provide the lateral openings 14 at the said end. The said end of the cap plate or top 13 is provided with a central depending tongue 15 engaging the said end of the bottom or base plate 11, whereby the openings 14 extend into the said end of the case. The other end of the bottom or base plate 11 is provided with an upturned tongue 16 engaging the other end of the cap plate or top 13 to provide openings 17 in the last mentioned end of the case adjoining the sides. The first mentioned or inner end of the case is disposed between the parting strip 4 and the rack 6, it being understood that the case is disposed or seated upon the -meeting rail ofthe lower sash, and the other or outer end of the case extends to, or is flush with, the inner face of the lower sash, and is also spaced sufficiently from the stop of the lower sash, as to prevent the said stop "of levers 19 are fulcrumed intermediate their ends upon the pintles 18, the top or cap plate 13 being provided with apertures normally receiving the upper or free ends of the'pintles 18l and screws 18Lv being engaged to the free ends of the pintles to hold the top or cap plate inplace. lIhe arms of eachlever 19 are disposed at an obtuse angle relative to each other., and the-:free ends of the inner arms of thelevers are provided with diverging or angular fingers or tips 2O arranged to be projectedthrough the openingsv 14k to engage the slots or openings 5 and 7 of the parting stripv and rack 6 re.- spectively. The other or outer arms of the levers 19 pass through the openings 17 in the outer end of the lock case, and are provided at their free ends with the finger or thumb pieces 21, whereby the latch or catch levers 19'may be readily swung or oscillated properly.

In orderv to prevent the levers 19` from swinoine freel abowedleaf s-rin0 22 has- D D 7 C its terminals or end portions disposed or seated uponthe outer arms of the levers directlyadjoining the pintles or fulcrums 18 of the levers, the intermediate portion of the spring being pressed downwardlyby the top or cap plate 13 to cause the levers 19 to be frictionally held at the posit-ions to which they are set or swung. d

In order to secure the top orcap plate 13 upon the sides of the case, and in order to Y secure the case, as a whole, upon the meeting i rail of the lower sash.

rail of the lower sash, a pair of screws or other securing members 23 are passed through suitable apertures provided in the top or cap plate 13 and the bottom or. base plate 11 of the case, totake into the said The screws Q3 are disposed in the longitudinal median line of the ease, the outer screw being disposed directly beyond the transverse line connecting the pintles 18, whereby the spring 22 will be lockedl between the upper ends of the pintles 18 and the outer screw 23. In

lthis manner, the spring is prevented from being dislodged or displaced.

It is evident that the lock is of simple construction, the several parts thereof being readily assembled 4 and separated. Thus, when the top or capplate is removed, the latch levers may be readily dropped upon the pintles 18, and the vspring 2Q may be disposed upon the outer arms of the levers, so

that when the top or cap plate 13 is placed in position, the levers will be locked within the case, and the spring 22 will be brought upper and lower sashes may be readily slid 'any elevated position desired.

under tension. Conversely, when the top or cap plate is removed, the levers and spring may be readily removed for purpose of repair,replace1'nent or cleaning.

In use, when the finger pieces 21 are sep-l arated, the outer arms of the levers being swung against the sides of the case, will cause the fingers 20 to be retracted within the inner end of. the case, in order that the without interference, 1t being noted that the outer end of the case is spacedV from the stop of. the lower sash, in order that the finger or thumb pieces 21 may be conveniently and properly manipulated without interference. lNhen it is desired to lock the lower sash in position, the right-hand lever may befswung to project the finger or tip 2O thereof-sofas to engage the proper. slot 5 of the parting strip rack, whereby the lower sash will be locked in its lowermost, or at Similarly, when it is desired to. lock the upper sash either in its uppermost or at any lowered position, ,the left-hand lever 19 may *be swung to project the finger or tip 2O thereof vet linto engagement with the proper slot 7 of the rack 6 carried bythe upper sash. In this manner,it is convenient to lock the r,lower sash to the lparting strip or jamb, and

to lock the upper-sash to the lower sash, the latchor locking levers 19 being. independent of each other so that itl is not necessary to lock the two sashes simultaneously. Thus, should the openings or slots 5 of the parting 100 strip rack and the rack 6 not be inhorizontal alinement, it would be impossible to' engage both of the locking levers 19 simultaneously with the parting strip, and rack 6, so that it will be apparent that the present invention is of advantage, inasmuch as it permits the lower sash to be locked to the parting strip first, and the upper sash, after being properly adjusted, may then be locked in place. It is also possible and practical'to 110 lock the upper sash to the lower sash, without also locking the lower sash in place, so that both sashes may be slid or moved together, and may be locked at any position to which they are slid. g

From the foregoing, taken in connection with the drawings, the advantages and capabilities of the` present invention will be obvious without further comment, it being `noted that the objects aimed at have been 120 `carried out satisfactorily.

Having thus described the invention, what is claimed as new is 1. In a lock, a case, having lateralk openings at one end, and openings in its otherv `end adjoining the sides, and a pair of levers openings, and finger pieces projecting through the last mentioned openings.

2. In a lock, a case including a bottom having sides, and a top removably seated upon the sides, the bottom of the case `having upstanding pintles intermediate its ends and adjoining the sides, a pair of levers fulcrumed intermediate their ends upon the pintles, having angular fingers at one end projectable through the sides of the case, and having finger pieces at their other ends projecting beyond the respective end of the case, and a bowed leaf spring having its terminals seated upon the levers and arranged to be pressed downwardly by the top ofthe case.

In testimony that I claim the foregoing as my own, I have hereto afIiXed my signature in the presence of two witnesses.
